New crater



Hi, all
This may be of interest.
Western Australian geologists have reported finding an impact crater inland
from Shark Bay. At 120 Km diameter, the Woodleigh crater is the 4th largest
in the world after Vredefort, Sudbury and Chicxulub. Dating isn't very
specific - between 364 (Permian) and 200 (early Jurassic) Ma.
Published in Earth and Planetary Sciences Letters v 177, pp 119 - 128
(2000) - this is an Elsevier journal and is apparently available at their
website.
So - do we now have a candidate impact for the Triassic-Jurassic mass
extinction?
